MUSIC TERMINAL AND CLASP.

. 7 Application an April 9,

The purpose of this invention is to provide a terminal member for music, adapted to normally retain the roll snugly wound on the spool. It consists of the elements and features of construction shown and described as indicated in the claim.

In the drawings: Figure 1 is a perspective view of a muslc roll on its spool, equipped with this inven- 10 tion, with the end portion unwound for a short distance for showing the terminal clasp position for engaging the drive pin of the take-up roll, also shown in the figure.

Figure 2 is a transverse section of such roll fully wound. with the clasp shown operating for holding it snugly wound.

Figure 3 is a detail section, longitudinal with respect to the music sheet, through the terminal lug andclasp, the several elements,

29 sheet, clasp and reinforcements, being shown 0 and particularly in placing the rolls into,

and withdrawing them from, containing boxes. To overcome this defect, I have provided a spring clasp member connected with and forming a substantial part of. the outer end portion of the roll sheet, and which is normally coiled with a diameter less than that of the roll when fully wound on the spool, so as to be adapted to react for closely clasping the roll when thus wound, the same being elastically flexible to permit it to be readily uncoiled or unclasped from the roll for unwinding the same and engaging the terminal with the drive pin of the take-up roll.

As shown in the drawings, the tapered terminal portion, a. of the note sheet forming the music roll, A, is reinforced by fabric laminae, B and C, said reinforcements being applied to the opposite surfaces of 9 said terminal portion of the note sheet; and

between them, at either the inner or outer side of the note sheet, there is secured a strip, D, of elastically flexible material, which may be a thin steel strip which extends to the extremity of the terminal ta- 1923. Serial No. 630,706.

pered portion, a, of the note sheet, and is normally coiled with a diameter, as above stated, materially less than that of the music roll fully wound on its spool.

For reinforcing the engagement of said terminal with the draft pin, E, of the takeup roll, F, the reinforcements, B and G, extend over the terminal portion, a, of the note sheet to a considerable width in comparison with the spring clasp, D; and said reinforcements being strongly glued to the note sheet over the excess area, they not only tend to retain the spring clasp in position against lateral displacement, but also distribute the stress of the spring,when it is straightened in pulling the note sheet from its spool, which stress might otherwise tend to rupture the note sheet,over a sufficient area to defeat such tendency and save the note sheet intact notwithstanding this stress.

Since the metal of the spring clasp will not be caused effectively to adhere to the paper note sheet, or to the fabric reinforcement, by any ordinary glue, said spring clasp member is secured to the note sheet and to the reinforcement by rivet eyelets, f and g at the two ends of such spring clasp, and the eyelet, at the outer end is made elongated and of proper dimension to serve as the means of engaging the draft pin of the talreup spool.

The normal diameter of the coil of the spring clasp being, as stated above, less than that of roll fully wound, and thereby not much greater than the diameter of the take-up roll, I it will result that when the operator, taking hold of the lug, a in which the note sheet and spring clasp member terminate, pulls upon the note sheet to unwind it from its spool, the spring clasp is straightened out nearly flat as to all that part back of the part immediately engaged by the operators finger, and the end portion thus engaged is thereby left extending at a considerable angle to the remainder, and is readily engaged with the draft pin in the annular groove, H, of the take-up roll; and the stiffness of the spring clasp is not too great to permit it to be readily coiled to the reduced diameter necessary for winding the first'coil of the note sheet closely on the take-up spool.

I claim:

A music roll note sheet having a terminal for engaging the take-up roll of the player 10 forcement being Wide relativel} to the spring clasp the spring clasp being positively secured to the note sheet and to the fabric reinforcements by a rivet eyelet closely adjacent to the outer end of the spring clasp and dimensioned to serve' for engaging the draft pin of the take-up spool.

In testimony whereof, I have hereunto set my hand at Chicago Illinois,this {lth day of April, 1923. r THOMAS: M. FLETCHER.
